In this type of blasting, the blast nozzle has local containment (a shroud) at its end, and containment is usually accomplished through brush-lined attachments at the outer periphery and a vacuum inlet between the blast nozzle and the outer brushes. High-pressure acid tanks used in the mining industry (especially during gold refining), as well as tanks (called "accumulators") found in some older paper mills and perhaps in other industries, are often lined with a specialized tile or lead brick. 0000029049 00000 n containment secondary engineering control Vacuum blast nozzles (vacuum blasting is a variation on open abrasive blasting). >> In addition, the coating being worked on may consist of several layers of lead-based paint, each of which could contain as much as 50% lead. %PDF-1.4 % This brick or tile is held in place with a specialized lead-containing mortar or grout. Generally, the sequence of events in setting up, tearing down, and moving of a containment structure on a bridge project is as follows: First, a section of the bridge is blast-cleaned and primed within the enclosure. Use of ventilation system like fume hoods, snorkels, etc. Evaluate Exposure Administrative controls are another form of work practice controls that can be used to influence the way a task is performed. Bags and containers must be labeled to indicate that they contain lead-containing waste. The health hazards in this activity are caused by the lead dust and paint chips produced in the scraping process. Soldering and brazing operations present similar health hazards (airborne lead fumes) but to a different degree. /Rotate 0 The health hazard in these operations arises from lead fumes becoming airborne. 0000003646 00000 n Consequently, appropriate controls must be implemented when using chemical strippers. Power-tool cleaning involves the use of power-operated impact, grinding, or brushing tools. Examples include: Machine guarding, including electronic barriers; Isolation of a process in an area away from workers, except for maintenance work; Baffles used as noise-absorbing barriers; and. >> The main ways to control a hazard include: Elimination: remove the hazard from the workplace. The exposure ranges assigned to the different categories of tasks are based on data collected by OSHA and other sources including two advisory groups. For the same reason, vehicles driven to the worksite should be parked where they will not be contaminated with lead. This figure illustrates the usage of a shrouded tool. 0000004973 00000 n The schedule should be adapted to exposure conditions at a particular worksite. Lead burning, a process by which virgin or alloyed lead is melted with a torch or otherwise fused to another lead object, is typically performed in maintenance operations on electrostatic precipitators or during the installation of lead shot, bricks, or sheets in the walls or floors of health-care x-ray units or industrial sites. /Type /Page Non-ventilation engineering controls can also include devices developed for the pharmaceutical industry, including isolation containment systems. Keep surfaces and debris moist when disturbing them. Certain lead-related construction tasks commonly produce exposures above the PEL and often orders of magnitude above the PEL. Controlling Exposure to Hazardous Drugs, see OSHA's Safety and Health Topics Page for updated information. Sponge jetting involves the use of specialized blasting equipment that propels a combination of an abrasive material (e.g., steel, garnet) encased in a soft sponge (foam) medium. Provide thermostatic control for heat guns to restrict operating temperatures to the lowest temperature that will allow for the effective removal of lead-based paint. This restricts the dispersion of the abrasive and thus the size of the area that can be cleaned. Use techniques with known low exposure potential such as encapsulation and removal/replacement instead of hand scraping with a heat gun. Although OSHA does not prohibit the use of methylene chloride-based stripping products, some local, State, and other Federal authorities may prohibit its use in residential units. /Font << engineering controls examples -glove boxes -biological safety cabinets -physical barriers of steel, plastic, glass -hand washing facilities -eye wash stations -sharps disposal containers -biological safety cabinets -ventilating laboratory hoods -autoclaves -safer sharps devices -air barriers or air "curtains" the continuous-flow respirators) should be used only for abrasive blast operations where the abrasive materials do not include silica sand and the level of contaminant in the ambient air does not exceed 25 or 50 times the recommended exposure limit, respectively. PECs all rely on a special type of high-efficiency particle air (HEPA) filter that is >99.99% efficient in removing particles as small as 0.3 microns in size (the most penetrating particle size [MPPS], which refers to the stream Recycling equipment must be well-maintained and regularly monitored to ensure it is removing lead effectively. Another good opportunity to use elimination and substitution is when selecting new equipment or procedures. >> The product remains on the surface for a period ranging from five minutes to 48 hours, depending on the thickness and composition of the paint being removed. 0000004177 00000 n General engineering and work practice controls that can be applied to almost any construction activity are addressed under Paragraph II, below. The companies providing this industrial cleaning service are hired to clean such areas as catwalks, structural beams, and floors to reduce worker exposure to accumulated dust and debris that results from normal operations. When recabling elevator ropes, it is necessary to secure the ends of the wire ropes in the baskets of thimble rods (sockets) at each end of the cable to keep the multi strand cable from unwinding. >> 2.2 Other Capture Devices 2.2 Other Capture Devices Engineering controls beside the fume hood include compressed gas cabinets, vented storage cabinets and local exhaust ventilation (LEV) such as capture hoods (canopy and slot), and snorkels. Identify and ensure the use of . An example of a partial containment is a structure with loosely hung permeable tarps and partially sealed joints and entryways. Strip back all lead-based paint for a distance of at least 4 inches in all directions from the area of heat application. /Resources << Dust generation is minimal, but dust can escape when cleaning areas are of difficult configuration because it may not be possible to maintain a seal between the tool and the surface in these areas. Use shrouded tools wherever feasible (shrouding can restrict accessibility to the work area) with vacuum attachment to collect dust and debris at the point of generation (Figure V:3-4). You will be subject to the destination website's privacy policy when you follow the link. Identify and use engineering controls. /T1_1 8 0 R A variety of heads are available to achieve a tight seal for inside corners, outside corners, and flat surfaces. The three principal projects involving the handling of lead shot, bricks, or sheets and lead-foil panels include the construction of linear accelerator suites, radiology (x-ray) suites, and industrial processing tanks. /GS1 14 0 R /T1_5 11 0 R In the industrial arena, some disadvantages of chemical stripping are that containment and collection of the waste materials may be difficult and productivity may be low compared with the rate for conventional abrasive blasting.

Structures that are typically cleaned by open abrasive blasting are bridges, tanks and towers, locks and dams, pipe racks, pressure vessels and process equipment, supporting steel, and metal buildings. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions. For all three groups of tasks, employers are required to provide respiratory protection appropriate to the task's presumed exposure level, protective work clothing and equipment, change areas, hand-washing facilities, training, and the initial medical surveillance prescribed by paragraph (d)(2)(v) of the standard (29 CFR 1926.62). /BleedBox [0.0 0.0 504.0 720.0] Overspray and rebound of the paint spray off the structure being painted increase the inhalation hazards to workers using lead-based paint. These cookies may also be used for advertising purposes by these third parties. In addition to the work practice controls previously described in Section B, the employer must provide training and information to employees as required by OSHA's lead in construction (. Developing administrative controls and safe work practices to reduce exposures to safe levels. Although airborne lead exposures are virtually eliminated with this approach, wet abrasive is more difficult to handle and move than dry abrasive, and the volume of debris also increases. and through the supply HEPA filters located When employee airborne exposures to lead are above the PEL, the employer must provide employees with a clean change area that is equipped with storage facilities for street clothes and a separate area with facilities for the removal and storage of lead-contaminated protective work clothing and equipment. Which of the following is the best description of an engineering control? The third model, which is a pressure-demand respirator, must be worn whenever silica sand is used as an abrasive material (NIOSH 1993). The primary exposure to fumes occurs while dipping the ladle into the lead pot, carrying the ladle by hand to the solder area, and pouring solder into the pipe joint. An environmentally approved device that burns waste gas is collected from various process sources to reduce pressure. These prioritized control strategies are called the "Hierarchy of Controls." Engineering controls include strategies that eliminate or reduce the hazard (silica dust) itself. Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Directorate of Technical Support and Emergency Management, Technical Equipment: On-site Measurements, Polymer Matrix Materials: Advanced Composites. /CropBox [0.0 0.0 504.0 720.0] To conduct these efforts, NIOSH works collaboratively with partners both in the United States and around the world. When vacuuming equipment is used, the vacuums must be equipped with high-efficiency particulate air (HEPA) filters. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. /Type /Pages The workers included in this group are those who are secondarily involved with other activities described above. because it is possible to exhaust the air from a Type A1 cabinet to the outside, Small quantities of volatile hazardous medications Removal and replacement is the process of removing components (such as windows, doors, kitchen cabinets, and trim) that have lead-painted surfaces and installing new components that are free of lead-containing paint. However, when used in confined spaces, the potential for creating an oxygen-deficient environment is significant and must always be guarded against. Knoy, T. 1990. Poles and hooks A torque of $0.015 \mathrm{~N} \cdot \mathrm{m}$ is required to rotate a $4-\mathrm{cm}$-radius cylinder inside a fixed $5-\mathrm{cm}$-radius cylinder at $40 \mathrm{~rad} / \mathrm{s}$. << The risk of silicosis is high among workers exposed to abrasive blasting with silica-containing media, and this hazard is difficult to control. 12.1-1 What are the types of engineering controls? CDC twenty four seven. The only difference in the provisions applying to the three categories of tasks is the degree of respiratory protection required. Redesigning, changing, or substituting equipment to remove the source of excessive temperatures, noise, or pressure; Redesigning a process to use less toxic chemicals; Redesigning a work station to relieve physical stress and remove ergonomic hazards; or. Brief descriptions of the facility and engineering concepts for the conduct of microbiological research are also provided. The shroud must be kept flush with the surface. To the extent possible, replacing lead chromate with zinc. An example is using plant-based printing inks as a substitute for solvent-based inks. If encapsulation is used over a surface covered with intact paint, little dust is generated and cleanup and waste disposal problems are therefore minimized. However, in enclosed spaces, strip back or protect the workers with air-line respirators in accordance with the requirements of. Three types of engineering controls are defined in <800>: 1. Administrative controls: programs and practic, Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer. Engineering control can also be said to be is a piece of equipment, a machine, or mechanical device designed to minimise the harm associated with a hazard. Administrative controls establish work practices that reduce the duration, frequency, or intensity of exposure to hazards. Ultrahigh-pressure water jetting utilizes pressurized water at pressures in excess of 25,000 psi. Engineering controls are the type of controls that protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. If the objective is to remove tight paint, productivity may be low. Installation and cutting of solid lead sheets, lead foil panels, and lead brick as well as the pouring of lead shot into cavities produce lead dust in varying quantities (Personal communication, G. Hyde, Baltimore Lead Burning Corporation, March 5, 1991). 0000010586 00000 n b. DNA only They include sharps disposal containers, self-sheathing needles, and safer medical devices, such as sharps with engineered sharps-injury protection and needleless systems. Filtered materials as well as other waste and debris should be placed in appropriately labeled, 6-mil plastic bags or sealed containers suitable for the transport of lead waste, and stored in a secure area pending disposal in accordance with State and/or local requirements. Pot dressing is another source of lead fumes. Power tools available for paint removal include needle guns, disc sanders, grinders, power wire brushes, rotary hammers, rotary peeners, and scarifiers. 0000017079 00000 n Cookies used to make website functionality more relevant to you. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker. The following engineering controls apply: Portable local exhaust ventilation should be used to remove lead dust and particulates from localized areas. Applying non-lead containing paints and primers. This means that it cleans more efficiently and removes tight paint and rust more effectively. Encapsulation refers to processes that makes lead paint inaccessible by covering or sealing the lead-painted surfaces. 0000020737 00000 n By directing a worker to position the exhaust hood properly or to improve work practice, such as standing to the side or upwind of the cutting torch to avoid the smoke plume, a supervisor can do much to minimize unnecessary employee exposure to airborne contaminants. Although this list of operations is extensive, it is not necessarily inclusive (i.e, other construction activities not mentioned here may also involve lead exposure). Substitution is using a safer alternative to the source of the hazard. Ensure that workers avoid the smoke plume by standing to the side or upwind of the cutting torch whenever the configuration of the job permits. the grout between the tiles/brick must be restored), repaired, or relined with an entirely new lining (either tile or lead brick). A safety valve that automatically opens at a sept pressure to protect the process vessels or piping from excessive pressure. /MediaBox [0.0 0.0 504.0 720.0] Documentation of encapsulation is important because of the potential for exposures to underlying lead-based paint during maintenance, future renovation, and eventual demolition. S. Use of Lead-Containing Mortar in Chemical (Acid) Storage and Process Tanks, T. Handling Lead Shot, Bricks, or Sheets, and Lead-Foil Panels, U. Reinsulation Over Existing Mineral Wool, V. Removal and Repair of Stained-Glass Windows. Engineering controlsreduce or prevent hazards from coming into contact with workers. The PEC is first cleaned with a germicidal detergent. 0000004636 00000 n /ProcSet [/PDF /Text] /T1_6 12 0 R You will be subject to the destination website's privacy policy when you follow the link. Containment structures that are provided with negative-pressure dilution ventilation systems to reduce airborne lead concentrations within the enclosure, increase visibility, and control emissions of particulate matter to the environment. /Font << Engineering controls, when feasible, are considered the first line of defense for avoiding exposure to bloodborne pathogens. The engineering control methods that can be used to reduce or eliminate lead exposures can be grouped into three main categories: (1) substitution; (2) isolation; and (3) ventilation. Small areas and areas with gross irregularities cannot be effectively sealed by the shroud. 1993. 0000004329 00000 n 0000020586 00000 n Prohibit burning to remove lead-based paint. Engineering controls besides the fume hood include compressed gas cabinets, vented storage cabinets, and local exhaust ventilation (LEV) such as capture hoods (canopy and slot) and snorkels, which capture and entrain chemical vapors, fumes, and dusts at the point of generation. The brushes prevent dispersion of the abrasive and debris as they rebound from the steel surface. Tarpaulins were generally used only to protect neighboring homes and automobiles from a damaging blast of abrasive or to reduce residents' complaints about overspray, dust, and dirt. /Length 1931 Lead Abatement Activities (Commercial/Institutional and Residential). Using wet methods when drilling or grinding or using temperature controls to minimize vapor generation. /Type /Page If feasible, design the facility, equipment, or process to remove the hazard and/or substitute something that is not hazardous or is less hazardous. This process (original enzyme $\rightarrow$ denatured enzyme) is endothermic and spontaneous. /CropBox [0.0 0.0 504.0 720.0] Three separate miscellaneous activities representative of the jobs performed by this group of workers are discussed below. Until the employer performs an employee exposure assessment and determines actual employee exposure, the employer must assume that employees performing one of these tasks are exposed to the levels of lead indicated for that task in this Appendix. /T1_0 16 0 R This figure illustrates a high-level overview of a dry-ice blast cleaning system. Dynamic Conditions relating to clean area classification under conditions of normal production. Engineering controls are the first line of defense in protecting workers from hazardous exposures. a device or room that provides an ISO Class 5 environment for the exposure of critical sites when compounding CSPs. Engineering controls reduce or eliminate exposure to chemical or physical hazards through the use of equipment or devices. Engineering controls, such as ventilation, and good work practices are the preferred methods of minimizing exposures to airborne lead at the worksite. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance. This is accomplished by pouring a tin-based babbitt material into the sockets to keep all of the strands in place within the socket. J-9-F-1-0011. Chemical stripping of old paint coatings is performed by applying solvent- or caustic-based strippers to the surface, either by hand or spray gun. Additionally, administrative controls and PPE are often applied to existing processes where hazards are not well controlled. Welding and cutting activities that potentially involve exposure to lead can occur as part of a number of construction projects such as highway/railroad bridge rehabilitation (including elevated mass-transit lines), demolition, and indoor and outdoor industrial facility maintenance and renovation. This could include changing the work process to stop using a toxic chemical, heavy object, or sharp tool. One of the most common flexible isolation systems is glovebox containment, which can be used as an enclosure around small-scale powder processes, such as mixing and drying. The hierarchy of controls has five levels of actions to reduce or remove hazards. A lead metal sheath is then slipped over the connection and the ends are sealed with molten lead. Figure V:3-1. They help us to know which pages are the most and least popular and see how visitors move around the site. The disadvantages of using water are that inhibitors may be necessary to avoid flash rusting, the containment must be designed to capture the water and debris generated by the cleaning process, wet abrasive/paint debris is more difficult to handle and transport than dry debris, and, unless the water can be filtered, it may add to the volume of debris generated. Blowing with compressed air is generally prohibited as a cleaning method, unless the compressed air is used in conjunction with a ventilation system that is designed to capture the airborne dust created by the compressed air (e.g. Another method is worker rotation, which involves rotating employees into and out of contaminated areas in the course of a shift, thereby reducing the full-shift exposure of any given employee. is, in fact, the velocity profile. Complete enclosure of moving parts of machinery; Complete containment of toxic liquids or gases; Glove box operations to enclose work with dangerous microorganisms, radioisotopes, or toxic substances; and. This page details the types of engineering controls used at UCL. These work to capture and entrain chemical vapors, fumes and dusts at the point of generation. /ExtGState << Process gases are compressible; liquids are not. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker. Biosafety Level 2 (BSL-2) BSL-2 laboratories are used to study moderate-risk infectious agents or toxins that pose a risk if accidentally inhaled, swallowed, or exposed to the skin. Failure to operate engineering controls properly may also contaminate the work area. /T1_2 11 0 R Workbench, Which one has Improved protection of operator: Engineering controls include Biohazard bags and labels PPE Sharps disposal containers Self-sheathing needles Work practice controls methods of working that reduce the likelihood of an exposure incident by changing the way a task is carried out. /TrimBox [0.0 0.0 504.0 720.0] NIOSH researchers help prevent occupational disease and injury by conducting engineering control technology evaluations and developing practical, solutions-oriented control technology interventions. Contract No. Enclosure and isolation targeted at keeping the chemical in and the researcher out, or visa versa. NIOSH. Although containment structures are designed to reduce the dispersion of lead into the environment, they usually increase worker exposure to airborne lead, reduce visibility, and increase the risk of slip and fall injuries due to waste material build-up on the footing surface of the enclosure. Exhaust ventilation must be equipped with an appropriate HEPA filtration/collection system. Partial containments refer to those that inherently allow some level of emission to the atmosphere outside of the containment. If the lead debris can be adequately filtered from the water, the volume of debris is low. Centers for Disease Control and Prevention. -the killing of all microbial life including microbial spores, -use of antimicrobial agents on inanimate subjects such as work surfaces, equipment items, agents not known to cause disease in healthy adult humans, agents with moderate hazardous potential to the personnel or environment, exposure potential to pathogens spread by aerosol inhalation, serious infection with possible lethal consequences, exposure to dangerous and exotic agents that have high individual risk of life-threatening disease that may be transmitted by aerosol with no vaccine or therapy available, handling materials in the lab setting without contact with blood or body fluids or infectious organisms, workstations where opened specimens are handled, activities which can result in the formation of aerosols, require handling of large volume of body fluids, or require prolonged exposure to body fluids, Introduction to Chemical Engineering Thermodynamics, Hendrick Van Ness, J.M. For example, employee exposure can be controlled by scheduling construction activities or workers' tasks in ways that minimize employee exposure levels. How do stiffness, density, and temperature affect sound waves? In other words, material, equipment, or an entire process can be substituted to provide effective control of a lead hazard. The removal and repair of stained-glass windows includes several distinct activities: Removing the glass from the building and tracing the location of the pieces of glass; Disassembling the lead strips ("came") and removing the lead putty seals; Cleaning or replacing of the individual pieces of glass; and, Only the first activity, removal, takes place at the construction site. Employers should correctly train workers and supervisors on how to use controls. 0000014770 00000 n Interlock systems for lasers and machinery are other good examples of isolating processes. Calculate the mass, in grams, of $\mathrm{NaCl}$ present in $54.3 \mathrm{~g}$ of $0.91 \% \mathrm{NaCl}$ solution. a. DNA and RNA This is especially true when used for multiple workers on a daily basis. 0000013048 00000 n Because of the water, little dust is generated. the primary means of containment developed for working safely with infectious microorganisms. Using local exhaust ventilation with proper filtration. This mortar is then used as pointing between the tiles or bricks. Some fundamental and easily implemented work practices are: (1) good housekeeping, (2) use of appropriate personal hygiene practices, (3) periodic inspection and maintenance of process and control equipment, (4) use of proper procedures to perform a task, (5) provision of supervision to ensure that the proper procedures are followed, and (6) use of administrative controls. All exhaust systems and vacuum equipment must be equipped with HEPA filters. /MediaBox [0.0 0.0 504.0 720.0] /ProcSet [/PDF /Text] Workers perform this work in relatively confined areas (such as an attic) or in an open bay structure. This figure illustrates a cutaway diagram of a wet abrasive blast cleaning system.
